Validity: Look at the population used for the VMQ and the populations for the tests used to evaluate the VMQ’s validity. Do you believe that the populations of the other tests are comparable…
For each of the tests of reliability and validity listed on the matrix, prepare a 50-100-word description of test’s application and under what conditions these types of reliability would be used as well as when it would be inappropriate. Then prepare a 50-100-word description of each test’s strengths and a 50-100-word description of each test’s weaknesses.…
This section should discuss the types of validity for which there is evidence and the adequacy of this evidence to support potential uses of the test.…
When measuring the validity of the survey I choice three basic approaches. The first approach was content validity. If the content of the survey has affiliation with the content that is being studied, then the survey has content validity. For example, a Manager Evaluation Survey for…
Bartlett's test of sphericity indicates whether the correlation matrix is an identity matrix, which would indicate that the variables are unrelated. The significance level gives the result of the test. Very small values (less than .05) indicate that there are probably significant relationships among the variables. A value higher than about .10 or so may indicate that this data are not suitable for factor analysis. Hence, the researcher concludes the data is suitable for factor analysis since Kaiser-Meyer-Olkin Measure of Sampling Adequacy value is .896.…

• Mean • Median • Mode Reliability and Validity: What Is…? Reliability • Consistency in measurement • Process must yield the same results when repeated Validity • Measuring exactly what you intend to measure Correlation and Cause Correlation Cause and effect • Relationship in which two (or more) variables change together • Relationship in which change in one variable causes change in another The Ideal of Objectivity • Objectivity – Personal neutrality • Value-relevant research – Topics the researcher cares about • Value-free research – Dedication to finding truth as it is, rather than as we think it should be Investigators should try to be objective in work.…
Validity – All decisions must be justified with clear referencing of the assessment criteria. In doing this another assessor should be able to award the same grade for the same piece of work.…
9 Reliability and validity. What strategies will you used to ensure that the data collection and interpretation accurately reflect the phenomenon?…
Developing a measure of a psychological construct is a difficult and extremely time-consuming process if it is to be done correctly. Construct validity is an overarching type of validity, and includes face, content, criterion-related, predictive and concurrent validity and convergent and discriminant validity. Convergent validity is demonstrated by the extent to which the measure correlates with other measures designed to assess similar constructs. Discriminant validity refers to the degree to which the scale does not correlate with other measures designed to assess dissimilar constructs. Basically, by providing evidence of all these variations of construct validity (content, criterion-related, convergent and discriminant), you are establishing that your scale measures what it was intended to measure. Face validity refers to whether a measure appears “valid on the face.” In other words, it means that just by…
The questions created for the survey instrument needed to represent the overall purpose of the study. To ensure that this was achieved, the survey needed to demonstrate validity and reliability. Validity, as described by Heale and Twycross (2015, 66), examines whether the specific concept has been accurately measured. In contrast, according to Floss (2013,1), reliability refers to the consistency of the instrument to measure the concept. The instrument needed to feature external validity in order for the data collected to be generalised (Heale and Twycross 2015, 66). To ensure the instrument was reliable, the questions featured limited answers to guarantee consistency in the replies and have the potential to be statistically analysed (Heale…

Symbolic convergence theory (SCT) is a general communication theory that offers an explanation for the appearance of a groups cohesiveness, consisting of shared emotions, motives, and meanings. Symbolic convergence theory provides a description of the dynamic tendencies within systems of social interaction that cause communicative practices and forms to evolve. This theory allows theorists and practitioners to anticipate or predict what will happen and explain what did happen. One thing SCT does not do is allow for prediction and control of human communication.[1]…
